In what remote way would the likes of Sandro and Klassen improve this lot? If for some bizarre reason you think either are good enough for this league and you even more bizarrely can't believe their exclusion, then go ahead and swop one clueless player for another. Those two wonder signings might well be at least as good as say DCL, or Lennon or Mirallas, but they are still crap players. As for the defence, well it picks itself because they are no worse than anyone on the bench.
I think you just hope someone like sandro can find some form. Barca didn't want him to go. He scored 16 la liga goals last season. Same with klassen. They might have something. We've seen an awful lot of DCL and I persoanllly don't think he'll ever get 16 goals in a quality league
Klassen didn't even make the squad. When you consider injuries and suspensions that means he's not even in our first 20 odd. Given everyone is shite why completely give up on him
